Small-cell networks play an important role in next generation mobile networks. Multiple antennas can be employed at the small-cell base stations (SBS) to further improve the spectrum-efficiency. However, the increased number of antenna elements induces more energy consumption, i.e., there exists a tradeoff between the energy-efficiency and the spectrum-efficiency. In this paper, the network performance...
One of the challenges for implementing 60GHz based wireless networks is the large amount of power consumption due to the large number of antenna elements. Decreasing the beamwidth of each link, each link obtains higher spatial reuse gain, however, the energy consumption is increasing dramatically due to the increased number of antenna elements. In order to tradeoff the energy consumption and the spatial...
